it could be a bad universal joint.
Check your universal joints!
Possible failed u-joint.
Sounds Like You Have a Bad Universal Joint In The Drive Shaft. Also somewhere in the drive trane there is a lack of Grease. Have it serviced and greased, but first have the universal joints checked and replaced if they are bad. Also check all Steering parts, and replaced if needed. Good Luck
IT COULD BE A WHEEL BEARING THAT IS BEGINNING TO GO OR the constant velocity shaft of the fwd unit. If you start hearing a "clunking" noise when you turn it's the shaft. In any event, it needs to be checked out by a good mechanic
it might be your drive shaft or transmission going out.
Seized or damaged half shaft (drive shaft) joint Usually this is a U joint type joint, but not always
I;m not sure if this the prob. but when you lifted the jeep did you re-align the wheels? Or the drive shaft could be at to much of a angle for the u-joints. with a lift the drive shaft will probably need to be lengthend. Most of these items will cause noise.
The chances are the shaft in question is most likely made of aluminium. The "tube"of the shaft will carry "noise" of the drive train. The covering is there to help limit the noise and vibration. It is more for dampening noise than a structural covering.
Typical U-Joint noise. Makes noise in reverse but not in drive. Check both front and rear U-joints of the drive shaft. If one is bad replace both. You do not want to go through R&R of the drive shaft twice.
If it's a clunk sound, check universal joint bearings and drive shaft bolts. Otherwise please describe noise.
It will cause both vibration and a knocking noise The vibration may feel like it is at the rear of of the SUV but be careful to have the drive shaft checked.
You bet it can. A bent or out of balance drive shaft will cause serious shaking. A defective U-Joint will also cause it to shake and is very dangerous.
